2. What distance did the cyclist travel in this time interval? 3. How much time passed during this time interval?
4. Use the distance and time information from questions 2 & 3 to calculate
the average speed of the cyclist during this time interval.
5. Compare the average speed of the cyclist in the first 60 seconds to this
last time interval. During which time interval was the cyclist travelling at
a faster rate? (Include evidence)
6. Compare the steepness of the line on the graph in the first 60 seconds to
the steepness of the line between 140s and 220s. Which line is steeper?

Match the following terms describing electrical events with the correct phases of the cardiac cycle. the ventricular muscle cells depolarize at the start of this phase. during this phase, na+ entry through the funny channels causes the pacemaker potential of sa nodal cells to gradually become less negative until it reaches threshold. the ventricular muscle cells repolarize right before this phase. the cytosolic concentration of calcium in the contractile cells of the ventricle is highest during this phase. a. isovolumetric relaxation b. ventricular ejection c. isovolumetric contraction d. ventricular filling
